Inclusion criteria

* A patient, or legal authorized representative (LAR), has provided informed consent and a written informed consent form. * Positive COVID-19 test. * Must be receiving medical care in an intensive care nursing situation. * Respiratory failure due to COVID-19 disease requiring invasive mechanical ventilation. This care may include but is not required to include the use of dexamethasone. * Within 18 hours of tracheal intubation to support invasive mechanical ventilation. A goal of this study is that T0 will occur within 24 hours of tracheal intubation to support invasive mechanical ventilation. * Age 18 to 80 years. * Males and females (females of childbearing potential who are not pregnant confirmed by a negative serum pregnancy test) and not lactating if recently post-partum). * Intent to deliver full supportive care through aggressive management utilizing all available therapies for a minimum of 96 hours.

Exclusion criteria

* Cardiovascular instability that precludes initiation of hemofiltration. * Irreversible brain damage based on available historical and clinical information. * Presence of any solid organ transplant at any time. * Patients with stem cell transplant in the previous 100 days or who have not engrafted. * Acute or chronic use of circulatory support device such as extracorporeal membrane oxygenation (ECMO), left ventricular assist devices (LVADs), right ventricular assist devices (RVADs), biventricular assist devices (BIVADs). * Metastatic malignancy which is actively being treated or may be treated with chemotherapy or radiation during the subsequent three-month period after study treatment. * Chronic immunosuppression defined as use of any immunosuppressant medications (cyclophosphamide, azathioprine, methotrexate, rituximab, mycophenolate, cyclosporine); prednisone use is excepted. * Patient is moribund or chronically debilitated for whom full supportive care is not indicated. * Concurrent enrollment in another interventional clinical trial except trials of COVID-19 convalescent plasma, anti-severe acute respiratory syndrome (SARS)-CoV2 monoclonal antibodies, or RemdesivirTM. Patients enrolled in observational studies (without the use of an investigative device or drug), are allowed to participate. Any communication between the Principal Investigator (PI) of this Protocol and the PI of any other clinical study will include the Medical Director of the Sponsor; all such correspondence will be documented. * Any reason the Investigator deems exclusionary

Design outcomes

Primary

MeasureTime frameDescription
Pulmonary Oxygenation FunctionUp to 72 hoursChange in patient Arterial Oxygen Partial Pressure (PaO2)/Fractional Inspired Oxygen (FiO2) Ratio

Secondary

MeasureTime frameDescription
Survival30 days and 60 daysChange in the total number of patients that survived
Hospital Costs 1Out to 60 daysChange in Hospital Utilization of ventilators (days)
Cardiovascular Vasoactive-Inotropic Score (VIS)Up to 96 hoursChange in score based on the calculation of the following medications used: dopamine dose (µg/kg/min) + dobutamine dose (µg/kg/min) + 100 x adrenaline dose (µg/kg/min) + 100 x noradrenaline dose (µg/kg/min) + 10 x milrinone dose (µg/kg/min) + 10.000 x vasopressin dose (U/kg/min)
Pulmonary Compliance of Respiratory System (CRS)Up to 96 hoursChange in patient oxygenation
Hospital Costs 3Out to 60 daysChange in Hospital Utilization of Intensive Care Unit (ICU) Hospital free days
Hospital Costs 4Out to 60 daysChange in Hospital Utilization of Renal Replacement Therapy (days on therapy)
Hospital Costs 5Out to 60 daysChange in Hospital Utilization (days hospitalized)
Hospital Costs 2Out to 60 daysChange in Hospital Utilization of vasopressor medication (days without use)

Other

MeasureTime frameDescription
Specific Blood Indicators 8Out to 14 hoursChange in blood lymphocyte count (%).
Hospital Acquired Infections (HAI) /Sepsis30 and 60 daysChange in the duration of days of diagnosed HAI/ Sepsis infections
Inflammatory mediators in bloodOut to 14 hoursChanges in inflammatory mediators detected by Immunoassay of Multianalyte Panel - MAP Laboratory Panel of 253 analytes.
Composite Survival30 and 60 daysSurvival without Respiratory Replacement Therapy (RRT), ventilator, or time to Long Term Care (LTC)
Composite Non-RecoveryUp to 60 daysSurvival with Respiratory Replacement Therapy (RRT), ventilator or in Long Term Care (LTC)
Composite RecoveryUp to 30 daysDuration without Respiratory Replacement Therapy (RRT), ventilator, and time to discharge
Cytokine Sieving EffectsOut to 8 hoursChange in cytokine levels obtained from plasma and blood collected prior to and after filter. Analyte concentrations in ultrafiltrate and plasma, expressed in the same concentration units, will be aggregated as a ratio of ultrafiltrate concentration to plasma concentration to yield a unitless Sieving Coefficient (SC). SC is an index of membrane function.
Specific Blood Indicators 1Out to 14 hoursChange in blood Ferritin (mg/mL)
Specific Blood Indicators 2Out to 14 hoursChange in blood Interleukin-6 (pg/mL)
Specific Blood Indicators 3Out to 14 hoursChange in blood C-reactive protein (CRP) (mg/L)
Specific Blood Indicators 4Out to 14 hoursChange in blood Lactate Dehydrogenase (LDH) (U/L)
Specific Blood Indicators 5Out to 14 hoursChange in blood D-dimer (mcg/L\*FEU2)
Specific Blood Indicators 6Out to 14 hoursChange in blood White Blood Cell (WBC) count (%)
Specific Blood Indicators 7Out to 14 hoursChange in blood Neutrophil count (%)
